When you need the heat illness prevention checklist

Heat illness can escalate quickly. New and returning workers are at higher risk in their first days.

Some states, such as California, have specific heat illness standards, and federal rules are developing. Check the rules for your location.

How to use the heat illness prevention checklist step by step

  1. Plan heavy work for cooler hours.
  2. Increase breaks as heat rises.
  3. Track water use.
  4. Check on new workers often.
  5. Review the plan each summer.

How one team uses it

On a 98°F day, a landscaping crew starts at 6 am, takes extra shaded breaks and finishes heavy work by noon. A new hire works shorter blocks for the first week.

What the heat illness prevention checklist protects you from

Heat illness can move from cramps to heat stroke within hours, and OSHA has used its general duty clause to cite employers who leave workers exposed to recognized heat hazards. A daily checklist shows that water, shade, rest and emergency steps were in place on the days the risk was highest.

Sample heat illness prevention checklist, filled in

Date July 22
Forecast High 101°F, heat index 108°F by 2 pm
Water and shade 3 coolers, 15 gallons; canopy at each work zone
Rest breaks 10 minutes in shade every hour after 10 am
New workers Eli, day 2, half-hour work blocks
Emergency Site address on truck dash, ice tub ready
Supervisor checks Dee, every 30 minutes

Sample for Cactus Ridge Roofing in Phoenix, Arizona. The heat index is filled in, not just the high, because it moves the day into a higher risk band, and breaks run by the clock so nobody has to ask to stop.

Mistakes with the heat illness prevention checklist

Tailor it to how you work

Warehouses and kitchensTrack indoor temperature, since hot indoor areas can be as dangerous as outdoor work.
Agricultural crewsBring water and shade to the field, since walking back to a truck wastes time and discourages breaks.
Worth knowingHave a cooler with ice and towels ready before the hottest part of the day. Fast cooling matters when someone shows signs of heat illness.

Common questions

Is there a federal heat standard?

Federal rules have been under development; some states have their own.

What is acclimatization?

Gradually increasing heat exposure over days.

Are breaks paid?

Rest breaks under 20 minutes are generally paid work time.

What are warning signs?

Heavy sweating, dizziness, confusion and more; train on them.

What heat index should trigger extra precautions?

Use the heat index rather than air temperature, since humidity keeps sweat from cooling the body. OSHA’s heat safety tool, for example, treats a heat index of 91 to 103 degrees as moderate risk and higher readings as high or very high, so write your trigger points on the checklist.

Do indoor workplaces like kitchens and warehouses need a heat plan?

They can, since ovens, dock doors and poor airflow can push indoor heat high enough to cause illness. California and Oregon have rules that reach indoor heat, and the same checklist works with readings taken inside.
